<hr />
<p>Probability and statistics are undergoing a substantial increase in both the breadth of scope and the mathematical technicality of many areas of specialization. There is a need for expertly written survey articles that will communicate an historic perspective on the successes, failures and general health of the area, as well as provide young researchers with a point of entry to the frontiers of the field. The Bernoulli Society plays a role in recognizing and communicating the importance of such scholarly efforts through a special award.</p>
<p>The Bernoulli Prize for an Outstanding Survey Article is to recognize authors of an influential survey publication in the areas of probability and statistics, respectively. The paper should be timely in addressing areas of active or emerging importance, but have been in circulation long enough for there to be evidence of its impact.</p>
<p>The award consists of the prize amount of 1000€ together with an award certificate. The amount may be adjusted in future years by joint request of committee chairs and approval of Bernoulli Council.</p>
<p>The combined awards are biennial. A paper in probability will be presented in a formal ceremony at the Bernoulli-IMS World Congress (BS-IMS-WC) in the summer of 2016, and a prize for a paper in statistics will be awarded in 2018, and formally presented at the ISI World Statistics Congress (ISI-WSC) in the summer of 2019, and each so awarded every four years, thereafter.</p>

<h3 id="lecture-1-random-walks-simple-and-self-avoiding">Lecture 1. Random walks: Simple and Self-avoiding</h3>
<p>The most common model for random behavior is the “drunkard’s walk” where at each time an individual chooses their step from some probability distribution. I will review this and then discuss what happens when one puts some constraints on the walker to try to avoid places already visited. We will see the relationship between the “fractal dimension” of the random path and the ambient dimension in which it lives.</p>
<h3 id="lecture-2-conformal-invariance-and-the-two-dimensional-critical-phenomenon">Lecture 2. Conformal Invariance and the Two-Dimensional Critical Phenomenon</h3>
<p>It was predicted by theoretical physicists that lattice models from equilibrium statistical physics “at criticality” in two dimensions have limits that are conformally invariant. There has been an incredible amount of work in the last twenty years making these ideas precise and rigorous and I will survey this work. The starting point was the development of the Schramm-Loewner evolution (SLE) which I will define.</p>
<h3 id="lecture-3-loop-measures-and-the-loop-erased-random-walk">Lecture 3. Loop Measures and the Loop-Erased Random Walk</h3>
<p>This talk will focus on two related models: loop measures and the loop-erased random walk which are closely related to uniform spanning trees and describe some relatively recent work in this area in dimensions two, three, and four.</p>

<h3 class="mt-5 mb-3">View from the Chair</h3>
<p>The last year was an eventful one for mathematics at UVa. We had a big year in terms of new tenured/tenure-track faculty. Two new assistant professors, Evangelia Gazaki and You Qi, joined our ranks, and we were also very fortunate to be able to recruit Ken Ono as the Thomas Jefferson Professor of Mathematics. Evangelos Dimou is joining our general faculty team that is focused on renewing our calculus program. Read ahead for profiles of all of our new faculty, as well as our new postdocs Bruno Braga, Anna Pun, and Charlotte Ure. It is particularly meaningful for me as chair to see the new faculty begin to shape the department and to assume their role as mentors for the next generation of mathematicians.</p>
<p>This year, we are gearing up for a major expansion of our postdoc program. One component of this relates to our ambitious plans to extend our smaller-class, interactive model for calculus to our applied calculus sequence. Smaller class sizes means more instructors, and additional postdocs will help with that. The other component relates to a large five-year NSF award to our topology-geometry group, which includes the hiring of two new postdocs each year for three years. Read ahead for an article on the new RTG grant (Research Training Grant).</p>
<p>Other highlights of this edition of the Virginia Math Bulletin include an article by Weiqiang Wang on his recent landmark work on Lie theory with his former student, Huanchen Bao, articles on undergraduate research projects conducted in the last year, and articles on activities of our AWM chapter (American Women in Mathematics). You can read about our Virginia Math Lectures by Fields medalist Andrei Okounkov and Pólya Prize winner Van Vu. There is an article about the career of Nat Martin, one of our emeritus faculty, who passed away this past year. He joined the department in 1959 and was a fixture here for nearly 40 years.</p>
<p>We are just now finishing up an intensive period of renovations to Kerchof Hall,
including a renewal of our lounge and kitchen area. The Math Lounge is a dream given form, giving a place for all of us to socialize, meet, and interact. I hope that whenever you are in town, you will take the time to visit and see for yourself by joining us for one of our Tuesday/ Thursday teas. Or should I say coffees? We are testing Rényi’s claim that a mathematician is a device for turning coffee into theorems.</p>
<p>I am particularly grateful for the support of the larger community of graduates and former members of this department. We are looking forward to another exciting year in the department, with new discoveries, involving our very talented graduate and undergraduate students, post-doctoral fellows, and faculty. Please enjoy this newsletter and let us know what you think. We hope you will stay in touch and I welcome your comments and questions.</p>

<!--more-->
<p>This award is based on two publications: the paper “Canonical bases arising from quantum symmetric pairs,” published in Inventiones Mathematicae, and the monograph “A new approach to Kazhdan-Lusztig theory of type B via quantum symmetric pairs,” published in Astérisque. In these works, Huanchen Bao and Weiqiang Wang completely extended the known theory of canonical bases from the case of quantized enveloping algebras to the case of quantum symmetric pairs.</p>
<p>In his 2015 UVa PhD thesis supervised by Wang, Huanchen Bao solved the longstanding problem of computing simple characters in the BGG category of modules over a simple Lie superalgebra g of type B/C. To that end, Bao and Wang developed a theory of canonical bases arising from quantum symmetric pairs, generalizing Lusztig’s construction.</p>
